The four IOO PZTs have been turned on in order to confirm the alignment of the IFO.
Once they are turned on, the spots (ITMX/ITMY/PRM/SRM) on the REFL CCD have been easily found.
When the X-arm was aligned to the green beam, it is easily locked to TEM00. Also some LG modes were visible.
i.e. There is some room to improve the mode matching.
The transmitted green at the PSL table is a bit too high and clipped by the first mirror on the table.
No IR flashes were found in either arms.
The below are the range and the set values of the strain gauge readback for the PZTs.
When the closed loop buttons are activated the PZTs are fixed at those values, if no one touches the set point dials.
